Outdoor motion sensor light stays on — San Francisco, California
An outdoor motion sensor light that stays on continuously instead of cycling off after a set time wastes electricity and loses its purpose as a security deterrent. The usual culprits are a misadjusted sensitivity dial picking up heat from HVAC vents or passing traffic, a stuck relay inside the fixture, a faulty sensor module, or the fixture being left in manual-on mode after a power flicker. An electrician can recalibrate the sensor, replace the photocell or sensor module, and verify the wiring is correct.

Many SF Victorians retain knob-and-tube or early aluminum wiring that violates current code and poses fire risk. California's aggressive electrification drive — heat pumps, EV chargers, solar — frequently forces full panel upgrades, and CSLB licensing plus DBI inspection apply to nearly all work.
